      Precalculate trending projects · 8d729570767c
      Yorick Peterse authored
      This commit introduces a Sidekiq worker that precalculates the list of
      trending projects on a daily basis. The resulting set is stored in a
      database table that is then queried by Project.trending.
      
      This setup means that Unicorn workers no longer _may_ have to calculate
      the list of trending projects. Furthermore it supports filtering without
      any complex caching mechanisms.
      
      The data in the "trending_projects" table is inserted in the same order
      as the project ranking. This means that getting the projects in the
      correct order is simply a matter of:
      
          SELECT projects.*
          FROM projects
          INNER JOIN trending_projects ON trending_projects.project_id = projects.id
          ORDER BY trending_projects.id ASC;
      
      Such a query will only take a few milliseconds at most (as measured on
      GitLab.com), opposed to a few seconds for the query used for calculating
      the project ranks.
      
      The migration in this commit does not require downtime and takes care of
      populating an initial list of trending projects.

      Refactor TrendingProjectsFinder to support caching · f57359a08310

      == Public Projects
      
      This finder class now _only_ returns public projects. Previously this
      finder would also return private and internal projects. Including these
      projects makes caching data much harder and less efficient. Meanwhile
      including this data isn't very useful as very few users would be
      interested in seeing projects they have access to as trending. That is,
      the feature is more useful when you want to see what _other_ popular
      projects there are.
      
      == Caching
      
      The data returned by TrendingProjectsFinder is now cached for a day
      based on the number of months the data should be restricted to. The
      cache is not flushed explicitly, instead it's rebuilt whenever it
      expires.
      
      == Timings
      
      To measure the impact I changed the finder code to use the last 24
      months instead of the last month. I then executed and measured 10
      requests to the explore page. On the current "master" branch (commit
      1fb46e29f7cc) this would take an average of
      2.43 seconds. Using the changes of this commit this was reduced to
      around 1.7 seconds.
      
      Fixes gitlab-org/gitlab-ce#22164
